CVE-2025-21415 (CVSS score: 9.9) – Azure AI Face Service Elevation of Privilege Vulnerability
“Authentication bypass by spoofing in Azure AI Face Service allows an authorized attacker to elevate privileges over a network,” Microsoft in an advisory for CVE-2025-21415, crediting an anonymous researcher for reporting the flaw.
CVE-2025-21396 is a security vulnerability caused by a lack of authorization, allowing unauthorized users to gain elevated privileges on a network. It was discovered by security researcher Sugobet.
The tech giant acknowledged a proof-of-concept exploit for CVE-2025-21415 but confirmed that both vulnerabilities have been fully addressed, requiring no action from customers.
Microsoft is improving transparency by issuing CVEs for critical cloud service vulnerabilities, regardless of whether customers need to apply a patch or take other actions for security.
“As our industry matures and increasingly migrates to cloud-based services, we must be transparent about significant cybersecurity vulnerabilities that are found and fixed,” it noted back in June 2024.
“By openly sharing information about vulnerabilities that are discovered and resolved, we enable Microsoft and our partners to learn and improve. This collaborative effort contributes to the safety and resilience of our critical infrastructure.”
